Abstract

Objective: This study intended to evaluate the color match of porcelain samples of Ceramco, Noritake, and Vita by two shade guides of their systems from the viewpoints of the teachers in Department of Prosthodontics.Methods: In this study, five professors of Prosthodontics determined the color of four samples made out of three different types of porcelain, using Vitapan Classical and Noritake shade guides. Data were analyzed using descriptive statistics, t-test, and ANOVA (P< 0.05).Results: Samples made out of Noritake porcelain had a better color match with both determination systems; however based on ANOVA test results, these findings were not statistically significant. The average of color match in Vitapan Classical system and Noritake system was 40% and 43%, respectively. Although clinically, Noritake system compared to Vitapan classical system had better color match, t-test showed this difference was not statistically significant. Conclusion: Porcelain type and shade selection system had no effect on tooth color selection.
